Why Choose Kore In Charleston, SC?
We Use Commercial-Grade C9 LED Bulbs
We don’t use the same lights you’ll find at a big-box store. We install professional commercial-grade C9 LED bulbs because they provide a cleaner, brighter, and longer-lasting display
Brighter, Richer Colors
Our C9 bulbs produce vibrant, eye-catching colors that stand out from the street while maintaining a classic holiday look.
Built to Last
Commercial-grade bulbs are designed to withstand harsh winter weather, including rain, snow, freezing temperatures, and strong winds. They’re made for outdoor use and are significantly more durable than retail light sets.
Energy Efficient
LED C9 bulbs use up to 90% less electricity than traditional incandescent Christmas lights, helping keep your energy costs low throughout the holiday season.
Long Lifespan
Every strand is custom measured and cut specifically for your home. This creates perfectly straight rooflines without extra wire hanging down or lights that don’t fit correctly.
Safer for Your Home
LED bulbs generate very little heat compared to traditional bulbs, reducing fire risk and making them a safer option for your family and your home.
Why Exterior Interior Window Cleaning Matters
Outside glass takes the brunt of Charleston weather. Salt spray, pollen, and sprinkler minerals build up on panes, screens, and frames. Regular professional cleaning protects the glass and the parts around it, not just the view.
Limits mineral buildup
Sprinklers and coastal air can leave deposits that etch glass over time. Routine rinsing and pure water cleaning help prevent permanent spotting.
Protects seals and frames
Removing grit, algae, and mildew keeps moisture from sitting on caulk and seals, which helps reduce wear around edges.
Improves natural light
Clean exterior panes let more daylight in, so rooms feel brighter without haze or streaks.
Smoother window operation
Brushed and rinsed sills and tracks reduce debris that causes sticking or grinding when you open windows.
Cleaner screens and airflow
Washed screens trap less dust and pollen, which helps airflow when windows are open.

Frequently Asked Questions
How often should I schedule exterior window cleaning?
Most homes do well every 3 to 6 months. In coastal or high-pollen areas of Charleston, quarterly service keeps salt, pollen, and dust from building up and makes each cleaning faster and more effective.
What is included with exterior window cleaning?
We wash exterior glass, rinse screens, and brush sills and frames. Trouble spots like corners and edges get extra attention. We finish with a pure water rinse or a traditional squeegee method for a clear, streak-free result.
Do you use pure water poles or hand squeegees?
Both. For upper stories and large panes we often use a water-fed pole with purified water that dries spot-free. For ground level and detailed edges we use traditional scrubbers and squeegees. We choose the method that gives the best finish for your windows.
Can you reach high or hard-to-access windows?
Yes. We use extension poles, ladders, and safety gear to reach upper floors, skylights, and windows over landscaping. Let us know about any special access notes so we can bring the right equipment.
Do you remove and clean exterior screens?
Yes. We remove, wash, and reinstall standard screens whenever access allows. Some full-frame or brittle screens may need extra care. If a screen is damaged, we will show you before proceeding.
Can you remove hard water spots or sprinkler stains on the outside glass?
Often, yes. We use mineral treatments and safe pads to lift deposits. Severe etching cannot be fully removed, but we will test a small area and explain what improvement you can expect before we begin.
Can you clean salt spray near the coast?
Salt leaves a film that dulls glass and can mark metal frames. Our wash and pure water rinse remove that film and help protect hardware. Homes closer to the water may benefit from more frequent service.
Is the process safe for plants and landscaping?
Yes. We pre-wet sensitive plants, use the right soaps in low amounts, and rinse thoroughly. Tell us about any specialty plantings and we will add extra protection.
Can you clean French panes, grids, and divided light windows outside?
Yes. We use smaller tools and careful technique to avoid drips around muntins and trim so each small pane finishes clean.
Will pressure washing the house clean the windows too?
House washing removes grime from siding but does not finish glass to a streak-free standard. For best results, schedule exterior window cleaning with or after pressure washing.
Do you work year-round?
Yes. Charleston has a mild climate, and we clean in all seasons. If severe weather is expected, we will reschedule so you get the best result.
